Definitions

  • the specification relates to containers. More specifically, the specification relates to containers that are configured to provide a visual indication that the container has been previously opened.
  • Containers are used to store many types of items, such as foodstuffs, medicine, or numerous other types of materials.
  • U.S. Pat. No. 7,073,680 discloses a tamper-resistant container with tamper-evident features which includes a cover portion defining a outwardly extending peripheral flange, a base portion defining an upper peripheral edge, a hinge joining the outwardly extending peripheral flange with the base portion and an engagement mechanism for maintaining the peripheral flange adjacent to the upper peripheral edge when the container is closed.
  • the upper peripheral edge includes an upwardly projecting bead extending substantially about the perimeter of the base portion that is configured to render the outwardly extending flange of the cover portion relatively inaccessible when the container is closed.
  • the hinge includes a frangible section, which upon severing, provides a projection that extends out beyond the upwardly projecting bead of the upper peripheral edge of the base portion, for facilitating the disengagement of the engagement mechanism and removal of the cover portion from the base portion to open the container.

  • the pivot region comprises a plurality of non-frangible pivot edges, including a lid pivot edge and a base pivot edge that are each spaced laterally apart from the respective lid and base, and which pivot edges are connected along a line about which the lid can pivot relative to the base.
  • the base and lid hinge panels have respective inner surfaces facing each other when the container is closed, and at least a portion of the inner surfaces are spaced apart to form a gap therebetween.
  • the line of weakness can overlie the gap.
  • the lid hinge panel can be separable into the grasping portion and the flap portion by displacement of at least a portion of the flap portion downwardly into the gap.
  • the base hinge panel can comprise a downwardly extending recess (or hollow) defining the gap.
  • the line of weakness defines a plurality of curves, and when the one of the lid hinge panel and the base hinge panel is separated into the grasping portion and the flap portion, the plurality of curves provide a plurality of grasping protrusions along the grasping portion.
  • the curves present an edge surface that can be gripped by a user, by inserting a finger into the gap underneath the curved edge, and urging the curved edge upward to separate the lid from the base.
  • the pivot region is biased to pivot the flap portion away from the grasping portion when the one of the lid hinge panel and the base hinge panel is separated into the grasping portion and the flap portion.

  • the container 100 is generally configured such that after it has been unlocked for the first time, it provides visual evidence that it has been previously unlocked. Accordingly, the container 100 may be substantially tamper-resistant, tamper-evident, and/or tamper-proof. Further the container 100 is generally re-closeable, but not re-lockable, such that a user may re-close the container 100 as desired after it has been opened for the first time.
  • the container 100 comprises a base 102 and a lid 104 .
  • the base 102 generally defines a receptacle, which may receive various items to be stored in the container 100 .

  • the lid has a lid peripheral portion 118 .
  • the lid peripheral portion 118 is mountable to the base peripheral portion 116 to mount the lid 104 to the base 102 .
  • the base 102 comprises a bottom panel 106 , and a plurality of sidewalls 108 extending upwardly from a periphery of the bottom panel 106 .
  • the base 102 is generally square, and comprises four sidewalls 108 a - 108 d extending upwardly from the bottom panel 106 .
  • the base may be another shape, and may comprise another number of sidewalls.
  • the bottom panel 106 may be generally circular, and a single rounded sidewall may extend upwardly therefrom.
  • the bottom panel and sidewalls may be substantially integral with each other, with out a clear delineation therebetween.

  • the peripheral portion 116 of the base, to which the peripheral portion of the lid 118 is mounted, extends from the upper portion of the sidewalls 108 .
  • the peripheral portion 116 of the base 102 defines a peripheral edge 121 of the base.
  • the lid 104 comprises a covering portion 110 , which generally serves to cover the receptacle 102 .
